To all whom it may concern.-

Be it-known that 1, WILLIAM ATKINSON MILNE, lumbernian,'of the villageof Browns Corners, in the county of York, in the Province of Ontario,Canada, have invented certain new and useful Improvements in Peat-Presses, of which the following is a specifi-.

cation.

My invention relates to improvements in peat-presses; and the object ofthe invention is to produce an economically-operated machine of thisclass which will produce perfect briquets of peat of a superior anduniform density; and it consists, essentially, of two meshing gear-wheels secured on suitable shafts having bearings upon a suitable bedplate or frame, the one bearing being station ary and the otheradjustable, and two wheels, each on opposing shafts, provided withrecesses in the 'peripheries' alternately arcshaped and angular,theangular recesses on one of the wheels being designed to come oppositeto the arc-shaped recession the coacting wheel, so as to make thebriquet's, and the sides of the wheels at their tangential point beinginclosed by suitable bands suitably supported and fitting closely to thewheel, so as to form ends for the briquets, the parts beotherwiseconstructed and arranged in in deiail as hereinafter more particularlyeX- plained.

Figure 1 is'a perspective view of a peat-press constructedin accordancewith my invention.

Fig. 2 is a plan. Fig. 3 is a sectional detail looking upon theperiphery of oneof the forming-wheels. Fig. 4 is an enlarged sectionaldetail of the forming-wheels, showing the W mannerin which the briquetsare compressed and discharged.

In the drawings like letters of reference indicate corresponding partsin each figure.

A is the bed'of the machine.

B and B are the standards, which are suitably secured to one endof thebed and provided with suitable bearings b, in which the maindriving-shaft G is journaled.

C is a counter-shaft which is journaled in suitable bearings d, whichare held on the hinged portion 0 of the arms E, which are pivotallysupported on the bed A by studs a. The upper ends of the arms areconnected by a cross-rod F. l

G is a rod which extends through the boss f, formed at the upper end ofthe intermediate arm E, being rigidly heldtherein by nuts at each side.of the boss. The opposite end of the rod G extends through a boss b atthe upper end of the standard B. The rodG is provided with alimiting-nut g.

H H represent two braces, through the eyeshaped ends of which the rod Gextends at one end,-the opposite ends of the braces extending throughthe lugs 1;, formed on the end sleevesl I.

J is a spiral spring extending between the boss I) and the collar j onthe end of the rod G, such collar being held in position by a nutj'.

K and K are the gear-wheels, which are secured on the shafts O and C,respectively, such gear-wheels meshing, as indicated.

L and L are the forming-wheels, which are provided with peripheries,having alternative arc-shaped and angular recesses Z] and Z Z. Thewheels Land L are almost tangential, and are so arranged that theangular recesses of one wheel pass into thefinal compressing positionalways opposite the semicircular recess'es of the other wheel. It isabsolutely necessary that this should be so on account of the sweep thatthe angular recess takes as the wheels are rotating toward each other incompressing. If they are both angular recesses, the peat-block could notbe discharged.

' MandM'arebands,preferablymadeofsteel, which abut, the faces of theforming-wheels opposite the compressing-point. The bands are endlessbands and are formed of one or more layers, and in order to reducethe-frictionI provide at the back of the bands two endless chains ofrollers N and N, which pass Wheels being suitably driven frem the mainshaft 0 through the merlinm of the gears the pest passes clown into therecesses, which are approaching each other astlie forming-Wheels 1 thehighest compressingpeintc rotate, and thereby gradually increases indensity until it reaches the point directly on a, line with the lev elof the shafts, Whirl"; is As the ferns ing wheels are still caused torotate, the of the angular recess rese'ile from the ercshaped recess,and the blocks, now som ressecl, are gradually released by means of theopening'up of the recess by which they have been formed. 'It ispreferable in the 1, formation of-the blocks tnettlie projecting points.of the wheel forming the recesses slightly overlap, so as to completelyseparate v or cut away tile briquet when formed from the preceding one,which is silly formed.

Its'ill be seen that if the when being compressed should become so denseas to exert a breaking strain on the peripheral cavities thatsuchstrainwould be relieved by means 0f the adjustable bearing-erms E,spring-held, as hereinbefore described.

I By such a machine as l descriheit will be seen that thepower needed isreduces to 2; minimum, that the machine is elwsys ceznpressing", so thatthere is us lest time er no- W'neels might be arc-shaped, er therecesses in one wheel be ell angular enrl the other ere-shaped "Withoutdeparting: from the spirit of my invention,

What I claim as my invention is--- 1. In a peat-press lwo forming-wheelsboth having their peripheries divided inte eresliepecl and angularrecesses, the ercshsped recess of'one wheel being designed to comesubstantially opposite the enguler recess of the opposite wheel. whenthey are on a level with the shafts as they rotate as and for thepurpose specified,

2.

3.
